I'd love to drive one. I've driven the 5.3 with a 4spd, 6spd (own still) , and 8spd. Deep down, it's one of my favorite motors because I have over 500,000 trouble free miles between 3 of them. The new 10 spd in the HD gas is buttery smooth so I'd expect even more smoothness from the 1500 platform trans. Should be perfectly fine for what you need and beyond.
